Product Description:

The B-402-B-A1 is an electric motor produced by Kollmorgen as part of the Goldline B and BH Motors series. The unit serves as the primary rotary actuator in automated equipment, supplying commanded torque and velocity to motion-control axes on assembly cells, material-handling stations, and test rigs. It occupies the form factor common to the series and integrates with matched drives through sealed connectors. This layout supports dependable servo operation in machines that need repeatable motion and compact motor packaging. Because it is intended for automated axes, the motor suits applications with frequent starts, stops, and direction changes during normal operation.

Under continuous duty, the motor delivers 6.8 N-m of stall torque while drawing 6.4 Arms of current. At its rated shaft speed of 3000 RPM, the electromagnetic design yields 2.2 kW of mechanical power, providing a balance between torque density and speed range for medium-inertia loads. A back electromotive force constant of 67.2 VRMS/kRPM characterizes the voltage generated per unit speed and allows the drive controller to scale its voltage loop during regenerative events or dynamic braking. These electrical characteristics help the matching amplifier regulate current smoothly during acceleration, steady running, and deceleration.

For transient moves, the magnetic circuit can reach 19.8 N-m of peak stall torque, giving the axis additional headroom for acceleration or disturbance rejection. The armature’s copper network presents 2.60 Ohms of DC resistance and 50 mH of phase inductance, parameters that affect current ripple and the current-loop bandwidth used by the servo amplifier. The motor housing has an IP65 sealing rating, and the 8.4 kg mass helps the assembly handle heat between duty cycles. Installation uses a standard metric mount, and cabling is routed through screw-thread connectors set at a 90-degree orientation; mating plugs are not supplied. The right-angle connector layout helps keep cable bends controlled near the motor body. There is also a rear shaft extension to accommodate secondary feedback devices or mechanical couplings, and it can support accessory mounting without changing the main drive-end interface.
